Description

Es ist bekannt, die Bewegungs- und Kraftverhältnisse des Kniehebels dazu auszunutzen, daß z. B. bei gleich großen Ausschlägen eines die Bremse betätigenden Hebels die Bremsbacken zu Anfang einen großen Weg zurücklegen, dann aber bei sehr kleinem Weg mit großer Kraft angepreßt werden. Die Antriebskraft greift entweder unmittelbar an den Gelenken des Kniehebelpaares an, oder sie wirdIt is known the movement and force relationships to take advantage of the toggle that z. B. with equal deflections of a lever actuating the brake, the brake shoes cover a long distance at the beginning, but then be pressed with great force if the path is very small. The driving force either engages directly on the joints of the pair of toggle levers, or it will

ίο durch einen besonderen Hebel übertragen. Durch die mittelbare Kraftübertragung über einen Hebel wird erreicht, daß die Bremse von zwei voneinander unabhängigen Kräften betätigt werden kann.ίο transferred by a special lever. Through the indirect power transmission via a lever it is achieved that the brake can be operated by two independent forces.

Soll der Kniehebel in allen seinen Winkelstellungen annähernd gleiche Kräfte abgeben, so wird dies erfindungsgemäß durch das Einschalten eines elastischen Gliedes in eines der Kniehebelpaare erreicht, wobei das elastische Glied so abgestimmt sein muß, daß die Bremskraft einen bestimmten Höchstwert nicht überschreitet. Läßt sich die beabsichtigte Wirkung nicht durch ein Kniehebelpaar allein erzielen, so können mehrere Paare hintereinandergeschaltet werden.If the toggle lever is to deliver approximately the same forces in all of its angular positions, so this is according to the invention by switching on an elastic member in one of the Reached toggle lever pairs, the elastic member must be tuned so that the braking force does not exceed a certain maximum value. The intended effect cannot be achieved by a pair of toggle levers alone achieve, several pairs can be connected in series.

In der Abbildung ist schematisch die Anordnung für eine einfache Kniehebel-Schnellschlußbremse mit Gewichtsantrieb dargestellt. Wird das Kniehebelpaar 11, 12 durch die in seinem Gelenkpunkt 10 angreifende Kraft 1 gestreckt, so bewegt sich der Punkt 13 im Abstand der Hebellänge 15 um den raumfesten Punkt 17 nach links und überträgt auf das im Punkt 13 angreifende Bremsgestänge 18, 19 und über die Winkelhebel 20, 21 den Bremsdruck auf die Bremsbacken 22, 23, die zu Anfang der Bewegung schnell an den zu verzögernden Maschinenteil 16 herangeführt und dann mit starker Kraft bei geringem Weg an ihn angepreßt werden. Der rechte Endpunkt 14 des Kniehebelpaares ist drehbar und raumfest gelagert. Am Hebel 11 ist als elastisches Zwischenglied eine Feder 24 dargestellt.The diagram shows the arrangement for a simple toggle-type quick-acting brake shown with weight drive. If the toggle lever pair 11, 12 is replaced by the in its articulation point 10 acting force 1 stretched, the point 13 moves in Distance of the lever length 15 to the fixed point 17 to the left and transfers to the im Point 13 acting brake linkage 18, 19 and via the angle levers 20, 21 the brake pressure on the brake shoes 22, 23, which are to The beginning of the movement is quickly brought up to the machine part 16 to be decelerated and then be pressed against him with strong force with a small path. The right end point 14 of the pair of toggle levers is rotatable and fixed in space. The lever 11 is as elastic Intermediate member, a spring 24 is shown.

Der Antrieb zur Betätigung der Schnellschlußbremse kann nicht allein von Hand oder durch ein Gewicht erfolgen, sondern auch durch einen Motor oder durch andere geeignete Kräfte.The drive for actuating the quick-acting brake can not only by hand or be done by a weight, but also by a motor or other suitable Powers.
